Hi,
we'd like to reuse the patterns we defined in our XML datatypes for validating
data entered via the GUI, on a keystroke by keystroke basis. E.g., we defined:
What we would like to have is a class that takes the pattern and a string and
tells us whether that string is valid, invalid, or incomplete, but so far not
invalid.
E.g.: "212-" is incomplete, but not invalid. "212121" is invalid. "212-555-1212"
is valid and complete.
I would like to have a class XercesPatternValidator that I could use in a
fashion as shown in the pseudocode below:
class FaxNumberType {
public static final int VALID = 0;
public static final int INVALID = 1;
public static final int INCOMPLETE_BUT_NOT_INVALID = 3;
String value;
String pattern = "[\d] {3} + - [\d] {3} + - [\d] {4}";
public void setValue(String value);
public int validate() {
XercesPatternValidator xpv = new XercesPatternValidator();
if(xpv.isComplete(pattern, value) {
if(xpv.isValid(pattern, value) {
return VALID;
} else {
return INVALID;
}
} else {
if(xpv.isValid) {
return INCOMPLETE_BUT_NOT_INVALID;
} else {
return INVALID;
}
}
}
}
Is this possible inprinciple? What are the classes/interfaces we'd have to use
for that?
Thanks,
Thomas
